SPECIFICATION forming part of Letters Patent No. 538,942, dated May 7,1895.,

Application filed Feb uary 20, 1 895- Serial No. 539,101- (No model.

To all whom it may concern.-

Be it known that LlJOHN WOOD, of Long Island Oity,in the county ofQueens and State of New York, have invented a new and ImprovedOrimping-Tool, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved handcrimping tool which is simple and durable in construction, veryeffective in operation and more especially designed to quickly andfirmly crimp a cap on the flaring mouth of the spout of an oil can orother receptacle.

The invention consists principally of a disk, held on a stock, and handlevers pivoted on the said stock and carrying the crimping rollsadjacent to the edge of the disk.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figurel is a side elevation of the improvement. Fig. 2 is a transversesection of the same on the line 2 2 of Fig. 1. Fig. 3 is an invertedplan view of the same, and Fig. 4 is a side elevation of the improvementas applied and with the can and cap shown in section.

The improved crimping tool is provided with a centrally arranged disk A,adapted to engage the top of the cap to be crimped on the flaring mouthof the can,as illustrated in Fig. 4, and hereinafter more fullydescribed. This disk A is mounted to rotate loosely on the lower end ofa stock B carrying'the pivot O, on which are fulcrumed the two handlevers D D carrying'at their upper ends the handles'D and D adapted tobe taken hold of by the operator, to manipulate the crimping toolhereinafter more fully set forth.

The lower end D of the hand lever D is formed with a pin D on which ismounted to rotate and to slide loosely, a crimping roll on the top of anannular flange A, formed on the disk A, as is plainly shown in thedrawings. A spring F is coiled on the pin D and rests with its lower endon the lower part D of the lever D, the other end of the spring restingon the top of the roll E, to press the latter with its flangein contactwith the flange A. The other lever D is provided at its lower end D witha fork D from the ends of which project the pins D and D similar to thepin D and likewise carrying crimping rolls E and E mounted to rotate andto slide loosely on the said pins. Springs Fand F press on the crimpingrolls E and E to hold the latter with their flanges E in contact withthe top of the flange A.

By the arrangement described, the three crimping rolls E, E and E areplaced approximately equal distances apart on the top of the disk A, andeach crimping roll is formed with a lower flange E connected by anannular recess E with the under side of the flange E. Thelex'ers D and Dare pivotally connected near their upper ends by links G and Grespectively, with a pin G2 fltted to-slide vertically in slots B,formed in the stock 13, so that the outward opening movement of thelevers D and D is limited by the pin G resting against the upper ends ofthe slots.

It will be seen that the springs F, F F exert apressure on the lowerends D and D of the levers D and D, to move their upper ends apart asthe crimping rolls and E rest on the top of the flange A of the disk A,thus limiting the downward sliding movement of the said crimping rolls.

The tool is used as follows: The cap II, formed with an annular flangeH, is placed on the upper end of the spout lot the can I, and then thedisk A is placed on the top of the cap H, as illustrated in Fig. 4, withthe hand levers D and D in an outermost position, so that the crimpingrolls E, E ,E do not touch the flange H. The operator now presses thehandles D and D toward each other, to move the crimping rolls E, E, Einwardly, so that the flanges E of the said rolls, travelon the inclinedtop of the flange A, whereby the crimping rolls are caused to slideupward on their pins, and the springs F, F, and F are compressed, and atthe same time the annular recesses E of the crimping rolls, move incontact with the flange H of the cap H,ai1d by their inward and upwardmovements, cause the flanges to turn in under the flaring mouth of thespout I. It will be seen that this is done at three different places onthe cap, so

that the latter is temporarily fastened to the month. By the operatornow turning the crimping tool, the rolls E, E and E revolve and roll offon the flange H of the cap H, so as to crimp the latter under theflaring mouth of the spout I.

It will be seen that by the arrangement described, the disk A serves asan anvil, to properly permit the crimping rolls E, E and E to crimp theflange H in under the flaring mouth of the spout 1.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A hand crimping tool, comprising a stockadisk held on the stock, hand levers pivoted on the said stock, andprovided at their upper ends with handles and crimping rolls journaledon the lower ends of the said hand levers adjacent to the edges of thedisk, substantially as shown and described.

2. Ahand crimping tool, comprisinga disk held on a stock, hand leverspivoted on the said stock and provided at their lower ends with pins,and spring-pressed crimping rolls mounted to turn and to slide on thesaid pins, and having flanges resting on the top of the disk flange,substantially as shown and described.

3. A hand crimping tool, oomprisinga disk held on a stock, hand leverspivoted on the said stock and provided at their lower ends with pins,spring-pressed crimping rolls mounted to turn and to slide on the saidpins, and having flanges resting on the top of the disk flange, andlinks for limiting the movement of the said hand levers, substantiallyas shown and described.

4. Ahand crimpingtool,comprisingastoek, a flanged disk mounted to turnthereon, hand levers pivoted on the said stock and formed at their lowerends with pins, crimping rolls mounted to turn and to slide on the saidpins and each having an annular flange resting on the top of the saiddisk flange, and springs coiled on the said pins and pressing on thesaid rolls, to hold the latter in contact at their flanges with thedisk, substantially as shown and described.
